LACING-TIPPING IVLACHINE.l

Application filed August 2G, 1921.

To @ZZ 'wiz-ont t may concern.'

lle it known that I, CHARLES G. HULTMAN, a citizen of the United States, residing at Providence, in the county of Providence and State of` Rhode Island, have invented certain 'new and useful Improvements in a Lacing- 'llippi'n'g Machine, of which the following is a s 4iecification.

rllhis invention relates to a lacing tipping machine for applying a length of tipping material to a lacing; and the object of this :invention is to provide in such a machine a fixed die and a co-operating movable die, each having a set of blades adapted to act upon and fold a length of sheet material about a lacing, said blades being also adapted to indent or corrugate the tip after it has been applied to the lacing.

A further object of this invention is to provide a cutting member for severing the tip mid-way of its length after it has been applied to the lacing.

TWith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of my improved tipping machine showing the interengaging die-members, the movable member of the die being operated on an incline.

Fig. 2 is a central sectional elevation showing the operating lever as engaging the slide bar which carries the movable die.

Fig. 3 is an enlarged plan view of the slide bar and showing the cutter carrying block as slightly advanced therein in the performance of its severing action.

Fig. 4 is a top view partially in section showing the fixed and movable dies as separated and partly in section.

Fig. 5 shows the fixed and movable dies with their blades in engaging position.

Fig. 6 is an elevation showing the dies in the separated position.

Fig. 7 is an elevation showing the die-s in their closed position.

Fig. S is a section on line 8-8 of Fig. 6.

able die, and the two cutting bla-des mounted on the fixed die; also showing the recesses in the rear of the two fixed blades, through which the waste cut from the tip may be discharged.

Fig. 10 is a perspective view of one of the tip metal folding-blades.

Fig. 11 is a perspective View of one of the fixed cutting blades showing the recess in its side face through which the waste is conducted.

Fig. 19. is an enlarged top view illustrating the cooperating blades of the different dies as in the act of crimping or corrugating a tip aft-er having rolled the same onto a lacing fabric.

Fig. 13 shows a length of tipping material illustrating the shape into which one of its edges is rolled before this length is placed between the die blades to receive the lacing.

Fig. 1,4 is a greatly enlarged view showing this tipping strip in section and placed in the notch of the fixed blades ready to be rolled or folded about the lacing.

Fig. 1.5 shows the dies as nearly closed and the tip-strip in the act of being rolled or folded about the lacing.

Fig. 16 shows the dies as having been closed and the folding or rolling of the tipping material completed.

Fig. 17 shows the tipping strip as having been applied to a lacing and severed at its middle portion.

Fig. 18 is a greatly enlarged transverse section through the lacing and tip after the latter has been applied to the lacing.

It is found in practice desirable to provide a lacing tipping device wherein a length of sheet material of a width equal to twice the length of a tip may be readily applied to a lacing, the tip corrugated circularly, and subsequently severed approximately at its middle portion all by a single operation, and the following is a detailed description of one means by which this result may bc accomplished.

With reference to the drawings, 2O designates the frame portion of my improved lacing tipping machine, which is provided with ears 21, through which it may be bolted to any suitable table or base 22. This frame is provided with a guideway 23, which isl set on an incline relative to the base,VV and is also provided withacutaway portion-24, see Fig. 2, through the center thereof communicating with this g-uideway, and-in which lthe operated lever' 25 is pivotedly` mounted as-at 26, the lower end of which lever is provided with a cross-bar 28, adapted to be engaged by the foot of the operator for actuating the machine to vapply the strip of tipping metal to the lacing,

as presently described.' On the lowerl end of this frame adjacent to the bottom portion of the-inclined lguideway, I-have mount- 'cd lthe fixedportion ofthe diewhich compriscsessentiallya set or plurality of spaced apart blades 42,9, see-Figs.- 4 'and' 5, which are f clamped between the upper and lower plates 30 and llrespectively, by the screws v32.

The two middle blades 33, as best illustrated-in Fig.` 9, are oppositely beveled inwardlyior towards each other as at 34 to cooperate with the punch orvcuttervblade t35, which is mounted in the reciprocating slide-- bar, Apresently described, for the purpose of severing f the tip. a'fterl'having been rolled and` iapfpliedito the lacing.

The inner. surfaces off these two cutter blades at the rear of their cuttingfedge are recessedY as -at 86, toprovidea space or openingkv through i which wastefcut fromy the tip byztlie1fcutter may, be-freely discharged to` prevent clogging the action ofthe cutter v during'its cutting operation.v

Each of thevmetal rolling or foldingyblades `,29 isprovided with a semi-circular recess 37 onritsworlingedge, and ani-under fgrwardlyproyecting guidingv lip or portion a preferably beveled back-asat 89', .providing a1comparatively sharped-gef 40, whereby it is adapted ,to corrugate or'lform substantially circular indentations orrrecesses atspaced apart intervals alonglthe. length of the tip, causingthe'tipv to' firmly grip lthe fabric of the lacing to prevent its removel -therefrom and tosalso lend to the-tip a handsome-and attractive annular-ly ribbed appearance.

In o-rderito locateth'ese blades intheir,

required :spacedieapart arrangement, .I preferablyprovidc the innen facesz of Vb'oththe upper-fand lowerlclanipfplatesfSO and 3l with correspond-ing blade-receiving grooves 41 and 42 respectively, as best shown Yin Fig. 8, so that when these blades lare positioned-iin thes'ea'groovesxand the two plates'bolted together ontoz the spacer 'member 43, the blades must necessarilybein' proper :position relative to each other and also relative to those co-operating intereirgaging blades in theV slider-bar presently described'. The rear of this'spaccr-bari43 is provided with an opening 44, `to'permitthe free discharge ofthe waste cut .lfrom the flacing.

The-'stock around'ifthe-recess l37 being therein, the same being provided with al centralopeningl, into which the operating end 50 of the lever 25 extends. VIn the inner end of thiss'liiding'block is'ciXedf the cutterblade 35, which extends through between the blades-46 and-is adaptedlto sever the tip after beingapp-,liedv to they lacing. To cause 'th'isbloclrto function' 'so as to first roll the tipx onto the lacing and-subsequently movefforward to causethefcutter 35. to sever the lacing, I have providedfa yieldinggjresistance to the forward movement'ofthis blockin its slide-bar 45,. which resistance is in` the formy of two springs 5l, actin-gfu'pon the studs 52 'fixed' to the-outer vend-ofthis slideV block'.- I-have also' inserted fa strip of crushablematerial 53,-such2as a comllnination of'rubber and fabric, to be forcedfagainsta fixed' cross-bar 54 :inthe slide-bar, wherebyl thel combined resistance of the springs and this yieldable member causes the-slide-bar, under action =of its operating llever, to ad- Vance and roll or foldithe tipping strip about the lacing, andY when this has been done the resistance ofitheseseveral blades 46, against the rolled stock ofithe tip, prevents further forward movement ofv the slide bar 45,-then a continued yforward movement ofthe flever25 causes. thefsprings and the rubber' plate to yield sufficient-lyy to permit a furtherforward'advanoe of the slide'- block tol drive .itsfcutter'through. the tip and lacingLfabricfto severboth, after which the yblockretui-ns to its normal position in the bari-and kthefbar returnsto its rear or upwardposition inizits frame, opening the dies and [permitting lthe tipped Aand. severedy lacing to be removed'therefrom to be: replacedv by'- `fresh work.

i The operationy of my improved lacing tipping machine is as follows:

The operator sits facing the benchlon which the 4machine is mounted, withthe operating. lever 25 projectingy down intov position to be engagedl andfoperated byfoot action. The normal posi-ti'on-of the slidebar with `its blades 46' isasfshown in Figs.- 1 and v2, inv which the forwardly extending under lips of the two sets foffbl-adcs-29 and 46foverlapfeach other, providing a 'rest onto which the tip material 55-mfay bie-placed.k 'This tip material is preferably'- astrip of vsheetmetal of a-wdfthy "doubleLV the length of the tip when finished. One edge'fofthis tip material is previously bent up int-o the `form illustrated in Fig. 13, and is, while in this form, positioned to rest upon these under lips with the curved portion in the recess 37 of the fixed blades.

A lacing of double the required length is placed with its middle portion in the curved portion of this tipping metal, then by a. foot action upon the swinging lever 25, the slide-bar 4:5, with its blades 46, is brought downward and causes the free end of the tip metal to be folded, rolled or curled over the pi'eviously curved portion 56 thereof, as illustrated in Figs. 15 and 16, and a continued forward motion lof this movable die causes its blades to form circular indentations spaced apart along the length of the metal tip, as illustrated in Fig. 17. The resistance now caused by the engaging of the many blades upon the sides of the compressed tip, arrests a further movement of the slide-bar 45, when a continued forward action of the lever causes the block 48 to slide or move forward against its yielding resist-ing members in the bar and drive the cutter blade 35 through the tip, severing it at its center portion. The waste stock which is cut from the tip is forced through between the cutter blades into the space 36 beyond, to be finally discharged through the opening 4:4 in the spacer block 43.

This operation may be repeated very rapidly and the tips applied, corrugated and severed, forming two complete tips, at a single opei'ation of the machine. The device is extremely practical in its operation and by its use tips may be applied to the lacing and caused to grip the same so firmly that they cannot be removed therefrom, at the same time producing a tip which is very handsome and attractive in appearance.

The foregoing description is directed solely toward the construction illustrated,

but I desire it to be understood that I reserve the pi'ivilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
